Adjustable putter and related methods

ABSTRACT

An adjustable putter that allows a golfer to quickly and easily adjust the lie and angle of a putter. The adjustable putter features a ball and socket joint connection that allows a golfer to adjust the shaft of a putter within the upper socket opening. The adjustable putter allows a golfer to articulate the angle of the putter relative to the putter head without affecting the putter grip&#39;s alignment with the putter face. Inside the shaft is a torque tube with a set pin that enters a sphere within a socket, which causes the sphere to expand and frictionally fit into the socket to lock the putter shaft in place. In an alternative embodiment, the torque tube assembly that may be of various lengths, where a male connection tool may enter the side of the putter shaft at any point. It is at that point where the female hex connection of the torque tube assembly will be positioned for use with the male tool. Additionally, the adjustable putter allows a golfer to adjust the loft of the putter via different loft plates that may be inserted into a loft cavity at the bottom of the putter.

BACKGROUND OF INVENTION

1. Field of the Invention

The subject matter of this specification is in the field of a golf putter apparatus and related methods.

2. Background of the Invention

Golf is a popular sport played worldwide by men and women of all ages. Golfers constantly strive to improve and lower their scores through practice and changes in equipment. Also, golfers have their own unique swing that feels comfortable to them, so many golfers will choose equipment that suits their swing the best in an effort to optimize their performance. Different types of equipment are made with different types of specifications, such as irons, woods, putters, and balls, to complement each player. Currently, woods have become an area where equipment can be adjusted fairly quickly with a simple tool to help players achieve a desired shape or trajectory of a shot.

With that said, though driving the ball is important, whether dealing with a beginner, an amateur, or a pro, one of the most important aspects of the game is putting because it typically takes up more strokes over the course of a round than those used with any other club. That is, a golfer typically uses his or her putter on a course more than any other club in his or her bag. Therefore, one of the first areas golfers can look to when trying to improve their scores is their putting. However, no single putter or putting technique is suitable for every player. Golfers have different physical characteristics, such as height and arm length, which require different equipment specifications to ensure that the putter is in the best position to give the golfer an optimal chance to hit the ball with success. Additionally, golfers have their own preference when it comes to the type of putter they prefer and each golfer has a style or technique of putting that may be better suited with the specifications of one putter over another. Thus, one method of improvement is for a player to use equipment that is best suited to personal needs, whether that be because of the size, feel, design, lie, weight, offset, or loft of the club.

Currently, there exists some golf equipment that allows for club adjustment. For example, U.S. Pat. No. 6,623,372 by Beebe et al. (hereinafter “Beebe”) discloses a putter with an adjustable shaft and an adjustable hosel; however, Beebe's hosel can only be adjusted in one plane, whereas the current invention can be adjustable to any position within the upper socket opening. U.S. Pat. No. 8,419,564 by Solheim et al. (hereinafter “Solheim”) discloses adjustable length golf clubs; however, Solheim's clubs, and specifically the putter, cannot be adjusted at the hosel or on the putter's club head to create alternative shaft angles in relation to the putter head.

Therefore, no apparatus exists that allows a golfer to choose among a variety of positions and control the club head lie, loft, hand position, and axial rotation.

SUMMARY OF THE INVENTION

In view of the foregoing, it is an object of the present invention to provide an adjustable putter that allows a golfer to manipulate the lie and angle of the shaft in relation to the putter's club head.

It is another object of the present invention to provide an adjustable putter that allows a golfer to manipulate the shaft within the upper socket opening while controlling the grips relationship with the putter's alignment.

Generally, disclosed is an adjustable putter that allows a golfer to adjust the shaft and choose the optimal position for his or her own putting technique.

The shaft cap 50 can be epoxied to the top of the putter shaft 2 and helps guide the male tool 5 into the female connection 9. The shaft cap 50 also abuts the tube spacer 10 to prevent the torque tube from unthreading out of the shaft tip 19. In an alternative embodiment, the shaft cap 50 may feature a magnet that is attached or embedded within the shaft cap 50 to act as a fastener for a putter sensor that helps golfers measure data during a putting stroke. The putter sensor may also feature a magnet and the magnetic attraction between the shaft cap 50 and putter sensor may act as a fastener to hold a putter sensor to the end of the grip 1.

FIGS. 5A-C are close-up views of one embodiment of the female connection 9. FIG. 5A is a top view of the female connection 9. FIG. 5B is a perspective view of the female connection 9. FIG. 5C is a side view of the female connection 9. In a preferred embodiment, the female connection 9 may feature a female hex connection 14 and also feature a stopper 51 and a receptacle insert 13 a. The receptacle insert 13 a may be inserted into the first end of the torque tube 11 (see FIG. 6), the stopper 51, in absence of a tube spacer 10, can also serve to stop the torque rod assembly 6 from unthreading by abutting the bottom of the shaft cap 50.

FIG. 6 is a close up view of the torque tube 11 and the first receptacle opening 15 a at the first end of the torque tube 11 and the second receptacle opening 15 b at the second end of the torque tube 11. The first receptacle opening 15 a receives the receptacle insert 13 a of the female connection 9. The second receptacle opening 15 b receives the receptacle insert 13 b of the set pin (see FIG. 7B).

FIGS. 7A-C are close-up views of one embodiment of the set pin 12. FIG. 7A is a top view of the set pin 12. FIG. 7B is a side view of the set pin 12. FIG. 7C is a bottom view of the set pin 12. In a preferred embodiment, the set pin 12 also features a set pen receptacle connector 13 b, threads 16, and a tapered tip 17. In one embodiment, the set pin 12 may feature a female connection 18 at the tip of the set pin receptacle insert 13 b. The female connection 18 may serve as an adjustment means if a torque tube assembly 6 is not installed in a putter shaft. Thus, in an alternative embodiment, a shaft may feature a side entry in the shaft for a player to insert a male tool 5 into the female connection 18 to adjust the putter (see FIG. 19). Referring to FIGS. 6 and 7, the second receptacle opening 15 b of the torque tube 11 receives the set pin receptacle insert 13 b.

FIGS. 8A-C are close-up views of one embodiment of tube spacers 10. FIG. 8A is a top view of a tube spacer 10. FIG. 8B is a perspective view of a tube spacer 10. FIG. 10C is a side view of a tube spacer 10. In a preferred embodiment, distributed along the torque tube 11 is at least one tube spacer 10, which provides stability throughout the length of the torque tube 11 and helps minimize vibrations in a shaft 2 during contact with a ball. The tube spacer 10 is a cylinder that has a bore through the length of the torque tube 11. The tube spacer 10 adheres to either the inner diameter of the putter shaft 2 (See FIG. 2) via an adhesive, such as epoxy or to the outer diameter of the torque tube assembly. In another embodiment, a tube spacer 10 may be positioned to abut the shaft cap 50, which prevents the torque tube 11 and shaft tip 19 from unthreading out of the sphere assembly 7.

FIG. 9 is a perspective view of one embodiment of the golf putter. Referring to FIG. 9, illustrated is the sphere assembly 7, which may be inserted into the hosel 3 of a putter head 4.

FIG. 10 is another perspective view of one embodiment of the golf putter, with the sphere assembly 7 inserted into the hosel 3 of a putter head 4.

FIG. 11 is a close-up cross-sectional view of the sphere assembly 7 (see FIG. 10). Referring to FIG. 11, in one embodiment, the shaft tip 19 of the sphere assembly 7 features threads 27 for the threads 16 of the set pin 12 to rotationally secure the set pin 12 in the shaft tip 19 of the sphere assembly 7. The shaft tip 19 is also defined by an outer surface 29 that may adhere to the inside of a shaft 2 via epoxy. Still referring to FIG. 11, the sphere assembly 7 may also be defined by sphere cap threads 28, an upper socket 21 and a lower socket 25. In one embodiment, the upper socket 21 may have a lip 37. Residing in half of the upper socket 21 and in half of the lower socket 25 are two anti-rotation peg tracks 22 that are configured opposite of each other. The sphere assembly 7 may also be comprised of sphere segments 24 that are positioned substantially in the lower socket 25, a sphere cap 20 that is positioned substantially in the upper socket 21, and anti-rotation pegs 23 (ARP), which are positioned opposite each other and aligned with the ARP tracks 22. The sphere assembly 7 may also feature a female connection 26 on the bottom of the lower socket 25 to aid in assembly. The outer diameter of the sphere segments 26 collectively form the lower portion of the sphere structure and the internal structure of the sphere segments 26 collectively are configured to create an expansion chamber 36 and receive the tapered tip 17 of the set pin 12. Therefore, after expansion (i.e., when the tapered tip 17 completely enters the expansion chamber 36), the sphere segments 26 will contour to the inner surface of the upper and lower socket to form a friction fit and lock the putter shaft 2 in place. Additionally, as the set in 12 advances into the expansion chamber 36, an opposing force pulls the sphere cap 20 up and back out, where it will come into contact with, and compress against, the inner walls of the upper socket. Still referring to FIG. 11, the sphere cap 20 and the sphere segments 26 are individual parts that are not connected in any manner, but they may come into contact with each other when the tapered tip 17 of the set pin 12 does not occupy the expansion chamber 36.

FIG. 12A is a close-up view of the upper socket 21 and the lower socket 25. Referring to FIG. 12A, in one embodiment, the upper socket 21 may feature a lip 37, which is compatible with a blade style hosel of a putter. FIG. 12B is a close-up cross-sectional view of the upper socket 21 and the lower socket 25. Referring to FIG. 12B, the upper socket 21 and lower socket 25 are connected to each other via an interlocking mechanism 39. Still referring to FIG. 12B, at the center of the sphere's center of rotation are at least one ARP tracks 22, wherein half of an ARP track 22 lies within the upper socket 21 and the other half of an ARP track 22 lies within the lower socket 25. In a preferred embodiment, the upper and lower socket are adhered to the inner surface of a hosel 3 via an adhering substance, such as epoxy. In an alternative embodiment, the upper and lower socket may be threaded into a hosel 3.

FIG. 13A is a cross-sectional view of the shaft tip 19, which features set pin connection threads 27 and sphere cap connection threads 28 b. FIG. 13B is a close-up view of the shaft tip 19 with an outer surface 29 of the shaft tip 19 that can be adhered to the shaft 2 via epoxy. FIG. 13C is a top view of the shaft tip 19, which features a set pin bore 30 for the set pin 12 to enter.

FIGS. 14A-14D are various views of the sphere cap 20 of the sphere assembly 7. FIG. 14A is a top view of the sphere cap 20 and the set pin bore 30. FIG. 14B is a side view of the sphere cap 20, which may feature sphere cap threads 28 b that may be secured to the sphere cap connection threads 28 a of the shaft tip 19. The sphere cap 20 may also be defined by at least one ARP holder(s) 31, which are configured opposite each other and house the ARP(s) 23. FIG. 14C is a bottom view of the sphere cap 20 with a set pin bore 30 and a sphere cap flat face 33. The sphere cap flat face 33 will abut and push against the top of the sphere segments 24 during adjustment of the shaft of the putter. The set pin bore 30 is a centrally located bore that receives the tapered tip 17 and the set pin 12. FIG. 14D is a perspective view of the sphere cap 20 with the ARP bore 32, wherein an ARP 23 is press fit into position. In another embodiment, the ARP 23 may be integrated as part of the sphere cap 20. In another embodiment, the ARP 23 may be separate from the sphere cap 20 and threaded into position. In an alternative embodiment the ARP 23 may be separate and press-fit or epoxied into position.

FIGS. 15A-15E are various views of the sphere segments 24. FIG. 15A is a perspective view of the sphere segment 24. In one embodiment, there may be four sphere segments 24, however various other numbers of sphere segments 24 may be employed. The sphere segments 24 may be further defined by a sphere segment flat face 35 and a sphere cap ARP cut out 34 configured opposite of another sphere cap ARP cut out 34. The sphere segments' flat face 35 abut the bottom of the sphere cap 20 and is able to slide along the sphere cap flat face 33 (see FIGS. 14A-D). FIG. 15B is a top view of the sphere segments 24, which may feature an expansion chamber 36. The set pin bore 30 and the internal configurations of the sphere segments 23 collectively form an internal expansion chamber. FIG. 15C is a side view of the sphere segments 24. FIG. 15D is a top view of one segment 15 of the sphere segments 24. FIG. 15E is a side view of one segment 15 of the sphere segments 24. Referring to FIGS. 15B-15E, the expansion chamber 36 is tapered to receive the tapered tip 17 of the set pin 12. When the tapered tip 17 enters the expansion chamber and contacts the sphere segments 24, the sphere segments 24 will be pushed out and into the walls of the lower socket. In one embodiment, if the shaft is articulated enough to contact its boundary, the upper socket 21, the sphere segments 24 could be tilted enough to be in partial contact with the upper socket 21 as well as the lower socket 25 to form a friction fit and secure the shaft in place of the desired adjustment.

Referring to FIGS. 3-18, disposed within the putter shaft 2 is a torque tube 11 that extends from the top of the shaft 2 down to the hosel 3 of the adjustable putter. The first end of the torque tube 11 may feature a female connection 9 (See FIG. 4), such as a female hex connection, which receives a male connection tool 5, such as a male hex tool. The second end of the torque tube 11 may feature a receptacle opening 15, which receives the receptacle connector 13 b of the set pin 12. The threads 16 on the set pin 12 allows the torque tube assembly 6 to move up and down in a screw like trajectory within the putter shaft 2, to either insert, or remove the tapered tip 17 from the expansion chamber 36, thereby unlocking or locking the sphere assembly, which in turn adjusts the putter shaft in the players preferred position. In a preferred embodiment, when the grip 1 is installed over the putter shaft 2, there will be an opening at the tip of the grip 1. The opening allows a male connection tool 5 to be inserted into the tip of the grip 1 and putter shaft 2, and into the female connection 9. Placed over and around the female connection 9 is a shaft cap 50, which helps guide the male connection tool 5 that is inserted into female connection 9. This configuration allows a player to stand in a putting posture and adjust the putter while in a position that provides the player with an optimal point of view to observe the relationship of the putter head 4 and putter shaft 2 during adjustment. Once the male connection tool 5 is inserted, a user may turn the male connection tool 5 to rotate the torque rod 10 clockwise or counter clockwise, thereby locking or unlocking the putter shaft 2 into place. The first end of the torque tube 11 also features a tube spacer 10 located below the shaft cap 50. This tube spacer 10 located below the shaft cap 50, acts as a thread stop and prevents the torque tube assembly 6 and the set pin 12 from unthreading out of the shaft tip 19 because the tube spacer 10 will abut the bottom of the shaft cap 50 before the set pin 12 can unthread from the shaft tip 19.

FIGS. 16A-16C are various views of the ARP(s) 23. FIG. 16A is a side view of an ARP 23, which is cylindrical in a preferred embodiment. FIG. 16B is a perspective view of an ARP 23. FIG. 16C is a top view of an ARP peg 23. Referring to FIGS. 16A-16C, in a preferred embodiment, the ARP peg(s) 23 are press fit into the ARP bores 32 of the sphere cap (see FIG. 14D). The ARP pegs 23 a preferably positioned at the sphere's center of rotation, so that they do not interfere with the shaft movements during adjustment. In one embodiment, the ARP(s) 23 do not allow any axial rotation of the putter shaft because there is no space for side-to-side movement of the ARP(s) 23 within the ARP track(s) 22. In another embodiment, a small degree of axial rotation is possible because the ARP(s) have some space for side-to-side movement within the ARP track(s). In an alternative embodiment, complete 360 degree axial rotation is possible because the ARP(s) 23 are absent.

FIGS. 17A-17C are various views of the upper socket 21. FIG. 17A is a top view of the upper socket 21 and the surface of the lip 37. FIG. 17B is a side view of the upper socket 21, which may feature a lip 37. Referring to FIG. 17B, the upper socket 21 has an interlocking mechanism 39 to mate with the lower socket 25. The lip 37 is important for a blade putter hosel because it pushes rising epoxy during insertion away from the sphere cap bore 40. FIG. 17C is a cross-sectional view of the upper socket 21, which depicts the location of the lip 37, the interlocking mechanism 39, and half of an ARP track(s) 22.

FIG. 33A is a perspective view of one embodiment of the adjustable putter illustrating the shaft's range of motion. In use, as the shaft articulates, it may reach a boundary when the shaft tip 19 impinges on the upper socket 21. FIG. 33B is a top view of the upper opening of the upper socket 21. Referring to FIG. 33B, in one embodiment, when the opening is rectangular, there may only be a heel to toe shaft range of motion 40, which is also known as lie adjustment.

FIG. 34A is a perspective view of one embodiment of the adjustable putter illustrating the shaft's range of motion. Referring to FIGS. 34A and 34B, in another embodiment, if the upper socket 21 opening is circular, then there is a conical range of shaft motion 41 as illustrated in FIG. 34A. Thus, depending on the shape and size of the upper socket 21 opening, shaft range of motion can be restricted by an upper socket 21 opening that has no space for the shaft tip to articulate within the upper socket 21 opening, or limitless as the shaft tip 19 has space to articulate within the upper socket 21 opening. Referring to FIG. 34A, the putter shaft 2 may articulate forward, backward, side-to-side, and anywhere within a cone.

In use, in one embodiment, if a golfer wants to change the position of the putter shaft 2 from a locked position, the golfer may place a male connection tool 5 into the end of the grip 1 and into the female connection 9 on the first end of the torque tube 11. The golfer then rotates the male connection 5 tool counter-clockwise, thereby unthreading the set pin 12 from the shaft tip 19, which moves the tapered tip 17 out of the expansion chamber 36. As the tapered tip 17 is being pulled out of the expansion chamber 36, the sphere segments 24 and sphere cap 20 move away from the walls of the upper and lower socket 21,25, thereby loosening the friction fit and allowing the shaft 2 to be articulated. Once the golfer articulates the putter shaft 2 to a desired position within the upper socket opening, the golfer may re-insert the male connection tool 5 into the female connection 9 at the end of the grip 1 and rotate the male connection tool 5 clockwise to thread set pin 12 into the shaft tip 19, wherein the tapered tip 17 will enter the expansion chamber 36. As the tapered tip 17 enters the expansion chamber 36, the sphere segments 24 expand and push up against the inner walls of the upper and lower socket 21,25, and the sphere cap 20 is pulled up against the walls of the upper socket 21 to create a friction fit. Once the tapered tip 17 is completely in the expansion chamber 36, the putter adjustment is complete and the putter shaft 2 is once again locked in the players preferred position.

In a preferred embodiment, the adjustable putter's ball and socket joint may be comprised of a six (6) elements: (1) a set pin; (2) a shaft tip; (3) a sphere cap; (4) ARP(s); (5) sphere segment(s); and (6) upper and lower sockets. In an alternative embodiment, the adjustable putter's ball and socket joint may be comprised of five (5) elements: (1) a set pin; (2) a shaft tip; (3) a one piece design (sphere cap and segments are not individual pieces); (4) ARP(s); and (5) upper and lower sockets.

In an alternative embodiment, the sphere assembly may be a one-piece design, wherein a single structure is separated by vertical expansion slots. The top of the sphere structure is connected to the shaft tip by a thin section of metal or other rigid material and the outer diameter of each sphere segment forms a sphere. The internal structure of each sphere segment creates an expansion chamber that accommodates the set pin 12 through a centralized set pin bore. Anti-rotation pegs are positioned at the sphere's center of rotation and they are positioned between the sphere segments within the vertical expansion slots.

In an alternative embodiment, the sphere segment may have anti-rotation pegs that reside in the socket and align with the sphere's center of rotation. The expansion slots of the sphere act as tracks for the anti-rotation pegs to ride within.

In one embodiment, foam sheets, tubing, or spray may also be used to fill the space between the torque tube assembly 6 and the inner diameter of the putter shaft 2 for vibration reduction purposes. In this embodiment, the torque tube assembly may or may not have tube spacers 10 and the rest of the torque tube assembly 6 may remain the same.

In an alternative embodiment, the torque tube assembly 6 may be completely removed. In this embodiment, a set pin with a female hex connection may be threaded into the shaft tip and a long removable torque wrench may be inserted down the shaft to access and turn the set pin for adjustments.
